A rare-earth metal series alloy for storage of hydrogen is represented by a general formula of Rem1NiwAlxFeyMz as an atomic ratio (wherein Rem is at least one rare earth element such as Mischmetal, M is at least one of Cu, Nb, Si and Zr, and 2.5<w<5.5, 0<x<2.0, 0<y<2.0, 0<z<2.0 and 4.0</=w+x+y+z</=6.0). Further, the alloy is coated with a film of at least one of Pd, Cu and Ni having a thickness of 100-1000 ANGSTROM . |
